[0035] See also Figure 1 , Figure 1The utility model shows an intelligent charging system in one embodiment, which includes: a charging device intelligent control box for safely outputting multiple charging circuits, the charging device intelligent control box includes a multifunctional intelligent meter 100, a total load switch 200, at least one output circuit, at least one manual / automatic switch, an intelligent charging module 500 and a communication gateway 701. In actual application scenarios, such as hospital scenarios, the power supply in the general charging device intelligent control box adopts a three-phase five-wire system (single-phase power supply can also be used in special cases), and the multifunctional intelligent meter 100 can collect electricity in real time. In this example, the multifunctional smart meter 100 uses a three-phase multifunctional meter to display real-time three-phase voltage, current, power and power consumption, and can monitor the power supply status and power consumption; the intelligent charging module 500 has a multi-channel time control function, that is, different charging time periods can be preset; the power supply is distributed to each output circuit after passing through the total load switch 200, and each output circuit includes a solid-state relay. Each time control circuit in the intelligent charging module 500 is connected to the control end of the solid-state relay in the corresponding output circuit through the corresponding manual / automatic switching switch. The control end connects or disconnects the circuit between the input and output of the solid-state relay, and the manual / automatic switch can switch between two modes: forced power supply and intelligent power supply of the intelligent charging module. That is, when the corresponding manual / automatic switch selects the automatic mode, each time control circuit in the intelligent charging module supplies power to the corresponding intelligent charging socket through the control end of the corresponding solid-state relay. When the corresponding manual / automatic switch selects the manual mode, the power supply directly supplies power to the corresponding intelligent charging socket through the control end of the corresponding solid-state relay without passing through the intelligent charging module. In order to achieve remote control, the intelligent charging module 500 is also connected to a communication gateway 701. The intelligent charging system also includes a remote server 702 connected to the communication gateway 701 through network communication, and a user end connected to the server 702 through network communication. In this example, network communication is used between the user end and the server 702 to remotely control the specific power supply method in the intelligent power supply mode. The user end can generally be a mobile phone APP or a computer web page version setting and monitoring 703; the intelligent charging system also includes at least one charging socket, each of which is connected to the output end of the solid-state relay in the corresponding output circuit through a field switch.

[0036] In this embodiment, the model of the intelligent charging module 500 is MG-0416SK or MG-0616SK or MG-0816SK or MG-1016SK, which generally includes a main control circuit and a multi-way timing module. The charging socket adopts an intelligent charging socket, that is, an anti-overcharging socket with an intelligent detection circuit. Generally, the anti-overcharging socket may include a socket, a detection and protection circuit, a built-in solid-state relay, a status indicator light, etc. It can detect that the charging power is less than 30W and then cut off the power supply through the built-in solid-state relay after a delay of 60 minutes, thereby ensuring that the device is not overcharged to cause electrical fire hazards such as electrical connectors and batteries.

[0037] like Figure 1 As shown, in this embodiment, the charging circuit is provided with 6 circuits, that is, the output circuit is provided with 6 circuits, and the corresponding manual / automatic switching switch is provided with 6 circuits from the first manual / automatic switching switch 401 to the sixth manual / automatic switching switch 406, and the intelligent charging module has 6 circuits of time control function, and each circuit of time control circuit corresponds to one circuit of output. Each output circuit also includes a leakage switch and an arc protection switch, and the leakage switch is also provided with 6 circuits from the first leakage switch 311 to the sixth leakage switch 316, and the arc protection switch is also provided with 6 circuits from the first arc protection switch 321 to the sixth arc protection switch 326, and the output end of the total load switch 200 is connected to the leakage switch and the arc protection switch in sequence, and then connected to the input end of the solid-state relay. Similarly, the field switch is also provided with 6 circuits from the first field switch 801 to the sixth field switch 806, and the intelligent charging socket is also provided with 6 circuits from the first intelligent charging socket 901 to the sixth intelligent charging socket 906.

[0038] In order to remind the user of the current status of each charging circuit, the charging device intelligent control box also includes at least one indicator light. In this embodiment, the indicator lights are provided with a total of 6 indicator lights 601 to 606. Each indicator light is respectively connected to the output end of the corresponding solid-state relay for displaying the actual output status.

[0039] When the intelligent charging system is in use, the user only needs to connect the device to be charged to the charging socket, and then turn on the on-site switch to charge safely according to the set method. The number of on-site charging devices is evenly distributed to multiple leakage protection switches, and then multiple circuit safety protections such as solid-state contactors and arc protection switches are connected in series. The manual / automatic control switch has two working modes. When switched to the first mode, that is, the intelligent charging module outputs the control power supply, the intelligent charging module is connected to the power supply circuit, and personalized multi-segment time-controlled power supply is performed under the remote control mode of the user end, that is, automatic charging is set according to the energy-saving power consumption of the State Grid during the valley hours. For example, it can be set to power supply from 12 am to 6 am to achieve intelligent energy-saving charging, safe electricity use, etc.; when switched to the second mode, that is, direct power supply, the intelligent charging module is not connected to the power supply circuit, and forced power supply is provided. When the user needs emergency charging outside the charging period set by the intelligent charging module or the automatic control fails, the manual / automatic control switch of the used line can be temporarily adjusted to the second mode, and the forced power supply mode is used for charging without affecting the other lines.

[0040] like Figure 2 As shown, the smart charging system can also include an independent special charging room, which includes at least one charging parking area. In this example, there are 6 charging parking areas, which are arranged side by side. Each on-site switch and smart charging socket are arranged in the corresponding charging parking area, which is convenient for users to operate the switch and wiring nearby. Monitoring devices and smoke detection devices are also provided, which are located in the special charging room respectively, so as to facilitate real-time viewing of on-site conditions and prevent fires.

[0041] In summary, the intelligent charging system provided by the utility model provides safe charging protection for large-scale energy storage equipment from two aspects. On the one hand, each charging line of the entire system circuit is relatively independent, and has multiple technical protections such as overload protection, leakage protection, arc protection, current limiting protection, time limit protection, and full stop, ensuring the safety and controllability of the entire charging process, and the charging mode can be switched between forced power supply and time-controlled power supply according to actual needs. In the time-controlled power supply mode, the charging time can be remotely controlled, taking into account energy-saving effects; on the other hand, the layout of the special charging room can provide a safe charging environment for multiple large energy storage charging equipment at the same time, and the charging room is equipped with fire smoke alarms and real-time video monitoring, which further improves safety.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
